I worked at Quorum Business Solutions, Inc. full-time (more than a year)

Pros

The pay is great. If you are able to get an assignment where you're at a client site, the job isn't bad.

Cons

Everything else. The hours are long and every single moment of your time needs to be assigned to a ticket. If work is scarce and you can't allocate your time to an assignment, it's YOUR fault. Instead of doing real work, the CEO smugly walks around most of the day spying on people in an attempt to catch them doing something wrong.

Quorum provides a great launchpad for individuals and professionals wanting to learn about the IT as well as energy industries.

Cons

Quorum does not have many if any downsides at all, since a down for one individual may be a pro for others. The consensus on a potential con are strict estimate deadlines. However, this can be seen across the consulting industry and is not limited to Quorum.
